A Brief Exposure to Ultra-wideband Signaling

Ultra-wideband (UWB) techniques are based on the generation of extremely short digital pulses in the sub-nanosecond range (1 to 1000 picoseconds). The technology is vastly different from classical radio transmission. The extremely short pulses are gene...
Bruno Pattan, Federal Communications Commission
No Comments
Baseband pulses are video or carrier-less pulses of very short duration. Their spectral content is concentrated primarily from zero frequency through the microwave region of the spectrum. This tutorial attempts to describe some of the vagaries of these pulses and their use in ground penetration radars and communications. Figure...

Defense Priority Ratings: Know the Rules

Shawn Cheadle, Cougar Components Corp.
No Comments
From the time a Department of Defense (DoD) program lands on the classified "secret" document known as the Master Urgency List (MUL), most orders placed to complete that program will have a priority rating. Most contractors and subcontractors who deal with these orders must therefore have a working understanding...

Intermodulation Products for a Mixer Subjected to a Multi-carrier Signal

Use of a nonlinear mixer model to demonstrate how a transient simulation is used to predict the behavior of intermodulation products in a multi-carrier environment
Assaad Borjak and Taoufik Bourdi
No Comments
Technical Feature Intermodulation Products for a Mixer Subjected to a Multi-carrier Signal Applying a multi-carrier signal to a mixer leads to a large range of intermodulation products. To perform a link budget of a multi-carrier transmit-receive system, it is important to predict the location and magnitude of those intermodulation...

Topics in Communication System Design: Carrier Triple Beats

Analysis of carrier triple beats that create third-order intermodulation interference when two or more carriers are present in one channel
Howard Hausman
No Comments
Technical Feature Topics in Communication System Design: Carrier Triple Beats Howard Hausman Miteq Inc. Hauppauge, NY Intermodulation interference is typically calculated based on two signals present in the RF or IF bandwidth. When the bandwidth is less than an octave, even-order intermodulation products, such as second- and fourth-order intermodulation...
